CROSSING AND SWITCH.

SPECIFICATION forming part of Letters Patent No. 431,514, dated July 1, 1890.

Application iiled February 5, 1890. Serial No. 339,261. (No model.)

To all whom t may concern:

Be it known that I, NATHANIEL O. GOLD- SMITH, a citizen of the United States, and a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Combined Crossings and Switches, ot which the following is a specication.

The object of my invention is to provide a switch which will operate six sets of switchrails for a compound crossing and switch, so that railway-trains may be run crossing from one track to another, or switch from one crossing-track to another.

Another obj ect of my invention is to provide a three-throw switch-stand which will throw alternately the four sets of switch-rails by two motions of the stand, and another movement of the stand move the end switch-rails, opening or closing them as the case requires, all of which will be fully set forth in the description of the accompanying drawings, making v a part of this specification, in which- Figure l is a vertical section of my switchstand through 'y y, Fig. 4. Fig. 2 is a perspective view of the cam-plate, showing the grooves on the upper and lower sides. Fig. 3 is a plan of the top plate of the stand. Figs. 4 and 5 are sections through line a: Fig. l. Fig. 6 is an end elevation of the stand, showin gthe relative position of the operating-bars. Figs. 7, 10, and 13 are plan views of a combined crossing and switch connected to the switch-stand, showing the three different positions into which the switch rails can be moved by turning the crank-arm of the stand.4 Figs. 8, 11, and 14, are diagrams of the top cam-plate; and Figs. 9, 12, and 15 are diagrams of the position of thebottom cam-plate, showing their various positions in relation to the position of the switch-points shown, respectively, in Figs. '7, 10, and 13.

5 represents the base of the stand, which is a guide for the operating-shaft 10 and the lower operating-bars 3 and 4. A

6 represents the body or upright portion o .the stand strengthened by webs a, which at their intersection form a bearing for the operating-shaft 10. n

8 represents the crank-arm moving on the Theoperating-shaft 10 has 5 5 in Fig.4 2, in which friction-rollers c', secured 6o to the operating-bars, travel. These camgrooves consist of an eccentric orworking portion from n to o between two concentric or idle portions from 'n to m and from o to p.

' 1, 2, 3, and 4 respectively represent the 65 operating-bars which are guided in grooves cut between the bottom and top parts of the stand. These bars are provided with lugs c, to the ends of which the friction-rollers c are secured; .The bars are arranged two above and 7o two below the cam-plate, so that the frictionrollers on the two lower bars travel in the lower cam-plate grooves, and those on the upper bars travel in the grooves on the upper face of the cam-plate.l

To explain-the position of the grooves on the upper side of the cam-plate in relation to those on the lower side, it must be understood that Fig. 8 is placed directly on top of Fig. 9,-

with the rod 4 directly under the rod 1 and 8o the rod 3 directly under the rod 2. Figs. 4

,and 5 represent the cam-platesso placed.

In Figs. 7, 1l, and 12, P P represent switchrails connected together by switch-rods B,

and R R', S S', and T T represent switch-rails 8 5 connected together by the respective bars R, S and T. These are the switch-rails of al combined crossing and switch. N N represent switch-points connected by rod g, and O O represent switch-points connected-byV rod 79o c'. These are the movable point-rails used to replace the ordinary-rigid frog-pieces'. The operating-bar 1 is connected by the rod f and the link. f to the far side of the throwing device I). Bar 2 is secured by the rod g and the 95 link g to the switch -points N N. Bar 3 is secured through rod h and link h with the near side of the throwingdevice D, and the bar 4 is secured through rode' and link al. with switch-points O O` A- loo It will be observed in Fig. lthat the rod f is directly above the rod h. The device, which is shown in drawings 7, 10, and 13, which moves the switch-rails P P', R R', S S', and T T', is the same as that shown and described in patent issued to Charles Partington September 3, 1889, No. 410,560.

In Fig. 7 the switch is set so that a train may pass from A to A', or vice versa. In this position of the switch the operating-bars 2 and 3 are extended and 1 and4are drawn in.

These positions of bars and cam-plates are shown in Figs 9 and 8.

Mode of operation: As the lever 9 turns the cam-plate one-hall` revolution in the direction shown by the arrow-z'. e., from right to left-or until the lever 9 drops into the notch b', the friction-roller on the operatingbar 2 (sec Fig. 8) has traveled toward the right in the eccentric-groove of the upper cam-plate fromn to o and to the position shown in Fig. ll. During this operation the friction-roller on the operating-bar l is moved in the concentric portion of the groove of the upper cam-plate from m to n, and to the position as shown in Fig. 12. Bar 3, Fig. 9, has also passed through the concentric portion of the lower cam-groove from m' to n', and remains inthe same position in relation to the cam as shown in Fig. 9, while the friction-roller on the bar 4 has traveled in the eccentric portion of the lower cam-groove from n' to o', and it has moved to the left from the position shown in Fig. 9 to the position shown in Fig. 12. Thus it will be seen that the operating-bar 2 on the upper side of the ca-m and the operating-bar 4 on the lower side of the cam during this one-half revolution of the cam-plate have moved in opposite directions and the bars 1 and 3 have remained stationary. Inasmuch as the operating-bar 2 is connected to the switch-points N N' and has moved in toward the stand, it will be seen that the point N' will be pulled up against the stock-rail U, and the point N will be moved away from the stock-rail V, and likewise the operating-bar 4, which is connected to the switch-points O O' by means of rod and link, will be moved out or away from the stand, and the switch-rail O will be closed against the stock-rail V, and the switch-rail O' will be moved away from the stock-rail U, which resultant position of switch-rails, crank-arm, and operating-bars is shown in Fig. 10. This sets the switch for trains crossing from B to B', and vice versa. Now, if it be desired to move the train from A' to B or Ato B', the lever 9 and crank-arm are moved from the position shown in Fig. 10 to that position shown in Fig. 13 2'. e., from right to left-the friction-roller on the switchrod 1 (see Figs. 11 and 12,) travels in the upper eccentric groove from n to o, moving bar to left, and the friction-roller of the operating-bar 2 travels in the upper concentric groove from o to p without moving bar, and at the same time the friction-roller of the operating-bar 3 travels in the lower eccentric groove from n' to o', moving the bar 3 toward the right, and the friction-roller of the operating-bar A4 travels in the lower concentric groove from o to p' without moving bar. This places the bars in the position shown in Figs. 14 and 15.

Inasmuch-as the bar 1 is connected by rods and links to the far side of the throwing device l), which operates the switch-points P P R R', S S', and T T', and the operating-bar 3 is connected to the lower near side of this operating device, and inasmuch as they move at the same time in opposite direction by motion described in the aforementioned Partington patent, the switch-rails R and P' and S and T' will be closed against the respective stockrails, and the switch-rails P and R' and T and S' will be opened (shown in Fig. 13) and allow the passage of a train from A' to B or from B' to A. This completes the 4revolution through one hundred and eighty degrees, and by reversing the direction in which the lever` was thrown the switch may be moved into each one of the several positions shown 'in Figs. 7, 10, and 13.

The object of my invention is to provide a single upright stand which may set the switchrails of a combined crossing or switch for the y passage of trains in either direction over the tracks from A to A', B to B', A' to B, or A to B.

I do not limit myself to the particular device shown on the drawings and described in the Partington patent, No. 410,560, to move the switch-rails P P', R R', S S', and T T', but believe I am the first to use a single-lever stand to move alternately the switch-rails of a combined crossing or switch and the movable point-rails O O' and N N', which replace the ordinary fixed frogs of crossings. To accomplish this result, one of the upper bars and the opposite lower switch-bar are connected by suitable links to the inner switchmoving device, and the opposing bars are each respectively connected to the outside switch-rails; hence the switch-bars moving the inner switch-rails are moved only when the switch bars moving the outer switchrails are idle, and vice versa. The throwing device mentioned in the foregoing speciiication is adopted, because it is believed to be the best; but other equivalent devices maybe employed in lieu thereof.

Having described my invention, what I claim is- 1. A combined switch-stand having four sets of movable switch-bars arranged in pairs and mechanism for operating said pairs alternately by one lever, in combination with a combined crossing and switch having the four 'pairs of switches and two pairs of center vwith two pairs of center and four pairs of end switches, a railway-switch stand com- IOO IIO
